Is it true???
This is actually a very important topic and one I only learned about recently. I think everyone who has had this surgery and still visits this board should give their feedback as to whether they feel any irregularities --that would be quite helpful.
I can tell you the following: the surgeon I consulted with here who did a computer simulation of my surgery (from a 3-D CT scan of my skull) showed me that the two sides of my mandible are fairly asymmetric. He showed me that doing the advancement was going to cause one side of the mandible to "kick out" and that the bone would remodel on that side in a noticeably different way and that only a year AFTER surgery if this asymmetry bothered me he could go back and "shave" or contour the irregularities.
So yes, what Dr. yaremchuk has written seems VERY TRUE and POSSIBLE. I don't know how common it is though.
One question I have is that perhaps surgeons with a lot of experience such as Arnett, Gunson, Schendel know how to deal with these or forestall them somehow. I wonder for example, if the high number of bone grafts and HA paste which A/G use is meant to fill in and recontour the osteotomy sites with an eye towards preventing such asymmetry from occurring during the bone remodeling phase.
Preventing the "step-off" from a genioplasty I think is not that difficult, by the asymmetry of the sides of the mandible or maxilla which could result from surgery I think is far more problematic.
Actually, it would be great if Marisama, Tree etc., Antbee and anyone else who has had the surgery is aware of asymmetry at this point or irregularities, step-offs etc. on the lower or upper jaw contours. Or if anyone knows if there are any techniques surgeons use to prevent it.
To answer your question: YES it is a very real issue.
